I have to do a grayscale figure for the function show in fig1, using a density function, and obtain the picture from fig2. I have tried a lot of things, but at the end I don't know how to do it. The fig1 representes l vs vl(l) for different R values, but the density depends on l and R, no on vl. At the end, the only way I foud is: Make a grid, for an R value,go through all the [x,y] points, asking if the function vl is defined there and, if so, calculating the density, and then adding the values for all the R. It seems a really hard way of doing it, that's way I would like to know if anyone have other idea. I would be really thankful if anyone can help me, because I'm frustated with this problem Thank you very much, Illa --000e0cd29722118c750469d30fd1 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Hello,
